<--QBASIC CODE end
Now, go and search your computer c:\ directory for the file called: homepage.htm; and, left double click on it to run; your web browser software should automatically launch itself, and, so display the web page output. Right click within an empty space within the web browser page...and, choose View > Source...and, you will be able to see the HTML source codes which were used to originally write the web page with; though, the QBASIC code itself is not displayed but remains entirely hidden.
QBASIC GRAPHICS There any many different things you can draw in QBASIC; ranging from... -dots -lines -rectangles -circles -shapes empty/or, filled in(painted) -you can even do LOGO style programming to draw graphics with; by joining up connected lines -animations are possible, too ==== QBASIC BUILT-IN HELP FILE + CODE EXAMPLES In order to view the QBASIC built-in Help file...; first, load the QBASIC program itself...; and, then, do a combination key press of: [SHIFT] + [F1] Use the built-in QBASIC Help file to learn more about how to use these 'graphic related' commands, and, more...! The QBASIC Help file also contains plenty of 'example codes'; which you can just use 'copy & paste'; then, RUN...to see what the output effect will be...???
END '...END of program/halt program code execution. *NOTE*: There should be only 'one' END statement written inside of a QBASIC program. I have seen example code where they use multiple END statements; this is wrong!
Write a program that calculates the area of a triangle in QBASIC
a triangle then a square :)
The QBASIC program actually comes in 2 different flavors... A> QBASIC interpreter program: QBASIC Version 1.1 B> QBASIC compiler program: QBASIC 4.5/or, QB64/or, -etc. ...so, the answer is that this programming language comes in both forms: 'interpreter/compiler' versions; and, you have to select which of these you would prefer to download and use. *NOTE*: The compiler version of the language tends to be much larger; whereas, the interpreter version of the language tends to be small/very compact, indeed; thus, the interpreter tends to take up far less disk space. Many people start off their programming career by using QBASIC version 1.1 'interpreter' program; in order to learn 'how to' program. The interpreter version of the program can only create plain text (.bas) files; the which code CANNOT be shared with others; (not unless the persons who you are sharing this type of code with do already have a copy of the QBASIC interpreter program installed on their own computer). Then, later on, down the line...when they have become fully capable programmers themselves; they go and download a QBASIC 'compiler' program version, instead; which will allow them to go and create stand alone (.exe) program files that they can share with anybody. This is because (.exe) program files can RUN/execute entirely independently of the QBASIC program itself.
